Viewing a spammed user's page if not a moderator adds a trailing 'members' slug to URL

[r-a-y]

Just encountered this bug.

Steps to duplicate:

1. Make sure you have marked a user as a spammer. Next, either log out or login as a non-admin.
2. Try to view the spammed user's profile.
3. The URL will show - domain.com/members/SPAMMER/members/

I've attached a quick patch that fixes this by unsetting the component in the canonical stack if the displayed user is a spammer and if the current user does not have the 'bp_moderate' cap.

Yup, this looks like the right place to fix the issue.

In 7456:

Fix trailing 'members' slug when non-admins view a spammer's profile.

If we're on a spammer's profile page, only users with the 'bp_moderate'
cap can view subpages on the spammer's profile.

Users without the cap trying to access a spammer's subnav page should be
redirected to the root of the spammer's profile page.

This commit does this by removing the component in the canonical stack
when a user without the 'bp_moderate' cap is on a spammer's profile page.

Fixes #5207.
